FET Multiplexer Module Description
The FET multiplexer module provides high-speed switching (multiplexing)
for up to 32 channels. The module can be used as a scanning multiplexer
for a scanning voltmeter configuration, or as a stand-alone multiplexer in a
switchbox configuration. The channels are numbered 00 to 31. Each
channel provides a connection for High (H). Low (L) and Guard (G) are
common for all channels. The FET multiplexer module can switch up to
100,000 connections per second (100 K switches/sec).
The FET multiplexer module consists of a component assembly and a
terminal module. There are three different terminal modules, one for each
of the following applications: Agilent E1351A 16-Channel FET Multiplexer
Module, Agilent E1353A 16-Channel Thermocouple FET Multiplexer
Module, and Agilent E1352A 32-Channel Single-Ended FET Multiplexer
Module. The component assembly is the same for all three applications.
For information on the 16-Channel FET Multiplexer Module, see the
Agilent E1351A/E1353A User’s Manual.
The component assembly contains the VXIbus interface, the FET switches,
the analog bus connector and the digital bus. The terminal modules provide
connection points for the individual channels as well as monitoring points
for the tree terminals. The FET multiplexer module can be externally
triggered from the VXIbus backplane or through the digital bus handshake
lines on the front of the component assembly.

Chapter 1
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
For high-speed operation (100 K switches/sec.) the scanning list is
automatically downloaded into RAM on the multiplexer module.
Triggering for channel advance is from the two handshake lines on the
Digital Bus. The scanning operation does not require any intervention from
the mainframe CPU. This only applies for switchboxes or scanning
voltmeter configurations that have all FET multiplexer modules. For a
downloaded scan list in switchboxes, the trigger source must be
TRIG:SOUR DBUS or TRIG:SOUR IMM.
Multimeter Connection Points
Multimeters can be connected to the 32-Channel Single-Ended FET
Multiplexer Module with the analog bus connector or through the tree
terminals. For a scanning voltmeter configuration the analog bus connector
is generally used, and for stand-alone multimeters the tree terminals are
used.
Analog Bus
Connector
Tree Terminals
The analog bus connector provides a direct connection between multiple
multiplexer modules and also between a multiplexer module and Agilent
E1326/E1411 Multimeters. A ribbon cable is used to daisy-chain multiple
multiplexer modules together, and to connect a multimeter to the
multiplexer modules for a scanning voltmeter configuration. The
SCAN:PORT ABUS command automatically closes the appropriate tree
isolation switches to route closed channels to the analog bus. This
command must be executed in a switchbox configuration. A scanning
voltmeter automatically configures the multiplexer for the analog bus
connector.
Tree terminals provide an external connection point through the terminal
modules for the signals which are on the analog bus lines. Tree terminals
are the recommended connection points for connecting stand-alone
multimeters and external current sources for resistance measurements.
Switchbox and Scanning Voltmeter Connections
A VXIbus instrument is a module or group of modules which perform a
specified function. For the Agilent E1300/01 mainframe, the first module in
an instrument must have a logical address which is evenly divisible by 8
(16, 24, 112), and the rest of the modules in the instrument are numbered
consecutively. The instrument’s secondary address is the whole number
equal to the logical address divided by 8 (for a logical address of 16, 17,
18,…23, the secondary address is 02). For instrument definition in other
mainframes, see the mainframe manual. If an instrument consists of only
multiplexer modules, it is a switchbox configuration. If a multiplexer
module(s) is combined with a multimeter to form an instrument, that is a
scanning voltmeter configuration.

Switchbox
A switchbox is a multiplexer module or group of multiplexer modules
which form a single instrument. A switchbox can be connected to a
multimeter which is a different VXIbus instrument, to an GPIB1 controlled
multimeter, or to a stand-alone multimeter. The switchbox and the
multimeter have different secondary addresses. Separate configuration
commands must be sent to the switchbox and to the multimeter. The
following program illustrates the different addresses and the configuration
commands required. The GPIB interface select code is 7, and the
mainframe address is 09. The multiplexer has an instrument address of 24,
so its secondary address is 03. The multimeter is GPIB controlled, and has
a primary address of 22.

When the multiplexer(s) is combined with a multimeter to form a single
instrument, they become a virtual instrument, a scanning voltmeter. The
multiplexer(s) and the multimeter have the same secondary address. The
multimeter automatically configures the multiplexer, so the SCAN:MODE,
SCAN:PORT and TRIG:SOUR commands are not required. Channel
advance is from the digital bus handshake lines, so the count loop is not
required. The ARM:COUN command does not apply to downloaded scan
lists, so you cannot specify the number of cycles through the scan list. You
can, however, specify INIT:CONT ON for continuous scanning through the
scan list.
GPIB is the implementation of IEEE Std 488.1-1978

Digital Bus and Triggering
The Agilent E1352A can be triggered for channel advance from the VXIbus
backplane or through the digital bus handshake cable on the front of the
component assembly. Backplane triggering can come from GPIB computer
commands over the GPIB Bus or from the Agilent E1300/1301 Mainframe
"Event In" port. Digital bus triggering uses two handshake lines; channel
advance and channel closed. Channel advance (input to multiplexer)
triggers an advance, and channel closed (output from multiplexer) signifies
advance completed.

The Agilent E1326B multimeter has a digital bus port on the face plate and
connects to the multiplexer with the digital bus cable (see Figure 1-2). To
connect other multimeters for digital bus triggering, you must prepare
custom cables. Use a connector like the one on the digital bus cable
(Agilent part number E1300-61611). Connect the measurement complete
port from the multimeter to the channel advance pin, and the external trigger
to the channel closed pin. Connect the grounds for both signals to the
Digital Bus ground (second pin from right). You can use this cable to
connect an external multimeter to a switchbox, and then use TRlG:SOUR
DBUS (digital bus triggering). You can also order a custom cable with BNC
to digital bus connectors, Agilent part number E1411-80001.
Programming Language
The examples in this manual use the Standard Commands for
Programmable Instruments (SCPI) commands, BASIC and an HP 9000
Series 200/300 computer over the GPIB. Chapter 5 contains information on
SCPI command format. Appendix B contains details on the registers for
register-based programming.
Initial Operation
Use the following program to verify initial multiplexer operation by closing
a channel and querying channel closure. The computer interfaces to the
mainframe with the General Purpose Interface Bus (GPIB). The GPIB
interface select code is 7, and the mainframe address is 09. The multiplexer
has an instrument address of 24, so its secondary address is 03.
This example first resets the switchbox and then closes channel 02 of a
single multiplexer module (card number 1) in the switchbox. The program
next queries the channel closure state. A returned "1" shows that the
channel is closed, a returned "0" designates an open channel.

Warnings and Cautions
Warning
SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the multiplexer modules. Before you install any
module, disconnect AC power from the mainframe and from
user wiring.
Caution
MAXIMUM VOLTAGE/CURRENT. The maximum voltage that
may be applied between High (H), Low (L), and Guard (G)
terminals is 15 V dc or 10.6 V rms (15 V peak). The maximum
current is 1 mA per channel.
STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical
components in the multiplexer module, observe anti-static
techniques whenever removing a module from the mainframe or
whenever working on a module.

Multiplexer Card Numbers
Agilent plug-in modules installed in an Agilent VXIbus mainframe are
treated as independent instruments, each having a unique secondary GPIB
address. An instrument may be composed of a single plug-in module or
multiple plug-in modules. The card number identifies the module within a
switchbox or scanning voltmeter configuration. The multiplexer module
with the lowest logical address is always card number 01. The multiplexer
module with the next successive address is 02, and so on. Figure 2-1
illustrates the card numbers and logical addresses of typical single-module
switchboxes. Figure 2-2 illustrates the card numbers and logical addresses
of a typical multiple-module switchbox. Figure 2-3 illustrates the card
numbers of a typical multiple-module scanning voltmeter.

Figure 2-3. Card Numbers for Scanning Voltmeter
The logical addresses noted in Figures 2-1, 2-2, and 2-3 apply to modules
installed in an Agilent 75000 Series B Mainframe (Agilent model number
E1300/E1301) or in a mainframe with an E1405/1406 Command Module.
See the Agilent 75000 Series B Installation and Getting Started Guide or the
appropriate Agilent Command Module Manual for more information on
switchboxes and scanning voltmeter configurations, and logical addressing.
For uses in other systems or mainframes, see the appropriate manuals.
Setting the
Address Switch
The address switch (LADDR) factory setting is 112. You may have
changed the setting during module installation. Valid address values are
from 1 to 255. Refer to the Agilent 75000 Series B System Installation and
Getting Started Guide or the appropriate Agilent Command Module Manual
for addressing information. Otherwise, to change the setting, see Figure 2-4.

Selecting the Interrupt Line Number
The multiplexer module generates interrupts at the end of a downloaded
scan list. The interrupt line number switch determines which backplane
IRQ line will be used. Different mainframes and resource managers
recognize different backplane IRQ lines. The interrupt line number must be
set to the line number your system is programmed to recognize. Refer to
your mainframe manual.
Refer to Figure 2-5 to change the interrupt lines. Valid line numbers are
from 1 to 7. Set the interrupt line number to the mainframe interrupt
handler number.
Figure 2-5. Setting the Interrupt Line Number
Setting the Card ID Switch
The multiplexer module can be an Agilent E1351A, Agilent E1352A or
Agilent E1353A depending on which terminal module is installed. With a
normal connection, the terminal module will automatically configure the
module for the appropriate model. However, if you use an extender card
which does not connect the middle row of pins, you will have to set the
Card ID switch, see Figure 2-6. The ID numbers are:
Model
Value

Connecting Field Wiring
Leads for the individual channels are connected through the channel
terminals on the terminal modules. Multimeters and signal generators can
be connected to the tree terminals on the terminal modules. Figure 2-8
shows the terminal module channel terminals for the 32-Channel
Single-Ended FET Multiplexer Module.
Wiring Guidelines
• If possible, use shielded cables with the shields connected to the
Guard (G) terminals and to the low connection near the measurement
point.
• Be sure the wires make good connections on the screw terminals.

Connecting Multimeters and Signal Generators
Figure 2-9 shows how to connect the analog bus connector and the digital
bus handshake cable between multiple multiplexer modules and the Agilent
E1326B Multimeter. Use the cables shipped with the multiplexer modules
to make the connections.
Stand-alone multimeters and signal generators can also be connected to the
tree terminals. Connections to the tree terminals are made on the terminal
module. If the multimeter has "Voltmeter Complete" and "External
Trigger" ports that use an open collector TTL pulse, you can use a custom
cable to connect it to the digital bus for triggering (see “ Digital Bus and
Triggering” in Chapter 1).

Selecting Channels
Individual channels within a module or multiple-module instrument are
selected with the SCAN <channel_list> or OPEN and CLOSe
<channel_list> commands. OPEN and CLOSe <channel_list> immediately
opens/closes the specified channel. The SCAN <channel_list> command
creates a scanning list which can be downloaded into RAM on each module.
The INITiate command closes the first channel on the scan list, and the
selected trigger mode advances the rest of the channels.
The FET Multiplexer Module uses break-before-make logic so that a closed
channel is opened before the next channel is closed. Only one channel can
be closed at any given time on the FET multiplexer. You can, however,
have a channel closed on two different modules in the same instrument.
To address specific channels within a multiplexer module in a switchbox or
scanning voltmeter configuration, you must send the appropriate SCPI
command string with a specified card number (cc) and channel number
(nn). The card number refers to the multiplexer module within a switchbox
or scanning voltmeter configuration. The multiplexer module with the
lowest logical address in a VXIbus instrument is card number 01, and the
next consecutively numbered multiplexer module is card number 02.
Chapter 3
Using the Agilent E1352A FET Multiplexer Module
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
27
If you have more than one switchbox or scanning voltmeter configuration,
the card numbering sequence starts at 01 for each configuration. A channel
address is, therefore, a four digit number (ccnn). For channel 07 on card 02
the address is 0207. You can delete leading zeros, so 207 is also a valid
channel address. The channel address <channel_list> is in the form:
•
•
•
•
(@ccnn) for a single channel
(@ccnn,ccnn) for multiple channels
(@ccnn:ccnn) for sequential channels
(@ccnn:ccnn,ccnn:ccnn) for groups of sequential channels
The OPEN and CLOSe commands should only be used with the
single-channel format and for one unique application of the
multiple-channel format. You can close a channel on two different cards in
the same instrument (e.g., 102 and 208) at the same time. You cannot close
two channels on the same card at the same time (102 and 108). Closing a
channel automatically opens all other channels on that card.
CLOS (@102,208,309)
Closes 02 on card 1, 08 on card 2
and 09 on card 3.
Opens 102 and 208, closes 103
and 204; 309 left closed.

Connecting Switchbox Channels to Tree Terminals for
Making Measurements
Connect external multimeters to the A tree terminal. The SCAN:PORT
ABUS command closes the appropriate FETs on the A and B tree isolation
switches, so the channels that are closed are connected to both the analog
bus connector and the tree terminals. The A tree terminal is connected to
the H, L, and G lines, and the B tree terminal is connected to the I +, I- and
G lines. Figure 3-1 shows how to connect multimeters to measure channel
02 and channel 18.
SCAN:PORT ABUS
CLOS (@102)
CLOS (@118)

Comments
Selecting SCAN:PORT. The default value of SCAN:PORT is NONE for
reset and power-on. You must execute SCAN:PORT ABUS after each
power-on or reset. SCAN:PORT NONE disables the tree isolation switches
and disconnects the analog bus connector and tree terminal lines.
Closing Channels. The FET Multiplexer Module only allows one channel
per card to be closed at a time. You can close a channel on two different
cards in the same instrument at the same time.
The SCAN <channel_list> allows you to specify a list of channels to be
closed sequentially. The FET Multiplexer Module uses a
break-before-make procedure, so closed channels are opened before the
next one on the list is closed. The channels are advanced according to the
TRIGger mode selected.
Query Open/Closed Channels. The CLOS? <channel_list> and OPEN?
<channel_list> commands determine if the channel(s) in the channel list are
open or closed, respectively. (The query command does not determine if, in
the event of a hardware failure, the channel remains open/closed.) For
example, to determine if channel 109 is closed, execute:
CLOS? (@109)
A response of 1 indicates that the channel is closed, and a 0 indicates that
the channel is open. The reverse is true for the OPEN? <channel_list>
command. The response for the OPEN? and CLOS? commands are:
CLOS?
OPEN?
1 = Closed
0 = Open
1 = Open
0 = Closed
To find out which channel on a card is closed, use a channel list for the card.
CLOS? (@100:131)
and enter the response into a string variable. If channel 09 is closed, the
response will be:
0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
Note
30
You must read the response after sending a query command or the
switchbox will generate an error.

Connecting External Current Sources for Making Ohms
Measurements
SCAN:MODE RES superimposes a current source on the channel being
measured to provide resistance measurements. The current source can be
from an external multimeter connected to the B tree terminal or the
scanning voltmeter multimeter connected with the analog bus connector.
Figure 3-2 shows how to connect current sources to either connector.
Execute the following command:

Scanning a Range of Switchbox Channels
You can scan a range of channels of a switchbox consisting of single or
multiple multiplexer modules. Scanning involves sequentially closing each
channel on a range of specified channels. The selected TRIGger mode
determines when the channel list will advance. During scanning, the FET
which was previously closed opens before the next FET closes.
You can use any of the TRIGger modes to advance the channel list.
TRIGger:SOURce EXTernal requires an external trigger source to be
connected to the Agilent E1300/1301 Mainframe "Event In" port. For
computer controlled or GPIB triggering (TRIGger or *TRG) use
TRIGger:SOURce BUS. The OUTput ON command enables the Mainframe
"Trig Out" port to synchronize multimeters when not in the TRIGger:SOURce
DBUS | IMM modes.
For the fastest scan rate (up to 100 K switches/sec.) use the
TRIGger:SOURce DBUS. Use a custom cable (see “ Digital Bus and
Triggering” in Chapter 1) to connect the multimeter handshake lines
(Voltmeter Complete and External Trigger) to the multiplexer digital bus.
Example: Making
Voltage
Measurements by
Scanning
Figures 3-3 and 3-4, and the following commands, show how to make
voltage measurements by performing a single scanning cycle of all channels
on two multiplexer modules in a single switchbox. In the example, the:
• A Tree Terminals of each terminal module connect to each other and
to the multimeter in Figure 3-4. To connect the A Tree Terminals to
each other, use either the analog bus cables (shown in Figure 1-2) or
wire the terminals together between the terminal modules.
• GPIB Bus trigger command advances the switchbox channel list.
• Agilent E1300/E1301 Mainframe’s "Trig Out" pulse synchronizes
the switchbox with the multimeter.
• Multimeter GPIB select code is 7 and primary address is 22.
• Switchbox GPIB select code is 7, the GPIB primary address is 09,
and the GPIB secondary address is 14.
• Computer is an HP Series 200/300 Computer with BASIC using

Downloading a Scan List
The FET Multiplexer Module is primarily designed to be used as a
high-speed scanning switchbox or scanning voltmeter. To enable it to make
100,000 connections per second, the SCAN <channel_list> scanning list is
downloaded into RAM on the module. This download takes place
automatically when you use TRIGger:SOURce DBUS or TRIGger:SOURce
IMM. For a multiple-module switchbox, the entire scanning list is
downloaded to each module. The channels are advanced to the next channel
in the channel list without any direct intervention by the mainframe CPU
during the scan.
The scan list is not downloaded for a switchbox or scanning voltmeter that
combines both FET and relay multiplexer modules, or for
TRIGger:SOURce BUS | EXT | HOLD. The channel closings are controlled
by the mainframe CPU. Also, the ARM:COUNt <number> command does
not apply to downloaded scan lists. You can use INITiate:CONTinuous ON
for continuous scanning with downloaded scan lists.

Scanning Voltmeter Configuration with an E1326B
This example shows an Agilent E1326B Multimeter and an Agilent E1352A
Multiplexer combined into a single VXIbus instrument, a scanning
voltmeter. The secondary address for the scanning voltmeter is 03. Both the
analog bus connector and the digital bus connector are used. Once the
scanning starts, there is no intervention from the mainframe CPU. The scan
list is in RAM on the multiplexer, and the two handshake lines on the digital
bus control the triggering.

Commands for Scanning Switchbox Channels
Scanning multiplexer channels consists of closing a set of channels, one at a
time. The multiplexer has single, multiple, or continuous scanning modes.
See Figure 4-1 for the different commands used in scanning.
Using Scanning Trigger Sources
The TRIGger:SOURce command specifies the source to advance the
channel list. Figure 4-2 shows the different trigger sources. TRIG:SOUR
DBUS uses the digital bus handshake lines. You can use the TRIG[:IMM]
command to immediately advance the channel list while in the TRIG:SOUR
BUS or TRIG:SOUR HOLD mode. (Note that TRIG:SOUR IMM is not the
same as TRIG[:IMM].) To enable the Agilent E1300/E1301 Mainframe "Trig
Out" port, use the OUTP ON command. The "Event In" mainframe trigger
source is reserved with the TRIG:SOUR EXT command. "Trig Out" and
"Event In" are mainframe resources, and can only be allocated to one
instrument at a time.
Scanning with
External
Instruments
The examples in this chapter show different ways to scan channels of a
switchbox in an Agilent E1300/E1301 Mainframe. The operation is similar
to other Agilent VXIbus mainframes with Agilent command modules that
have "Trig Out" and "Event In" ports. The computer used in the examples is
an HP Series 200/300 used with BASIC as the program language. The
computer interfaces with the mainframe over GPIB. Assumed is an:

Handshake Triggering (TRIG:SOUR DBUS)
Uses digital bus on faceplate of multiplexer
module. Channel Advance and Channel
Closed continuously handshake with Voltmeter
Ready and Voltmeter Complete until scan list
has completed specified number of cycles.
Immediate Triggering (TRIG:SOUR IMM)
Sets immediate internal triggering. The
scan list is automatically advanced. Due to
the high speed of the FET multiplexer, this
mode should be used with consideration
for the capability of the multimeter. This is
the default trigger mode.
Advancing Scan (TRIG[:IMM])
This command advances the
scan list when in TRIG:SOUR
HOLD or TRIG:SOUR BUS.
Advances the scan list one
channel per TRIG command.
Trigger HOLD (TRIG:SOUR HOLD)
Prevents execution of triggers until trigger
source is changed. Can use TRIG[:IMM]
command to trigger a switchbox set to
TRIG:SOUR HOLD.
Bus Triggering (TRIG:SOUR BUS)
Defines trigger source as *TRG or
GPIB GET command. The scan list
is advanced one channel for each
*TRG or GET command received.
Enabling Trig Out Port (OUTP ON)
External Triggering (TRIG:SOUR EXT)
Trigger source is a user supplied input to
the Event In BNC. Use a +5 negative-going
pulse to trigger. TRIG:SOUR EXT reserves
the Event In resource so that it is not
available for any other instrument in the
mainframe.
Generates a +5V negative-going pulse each time
a channel advances. OUTP ON reserves the
TRIG OUT port so that it is not available for any
other instrument in the mainframe.
As an alternative to OUTP ON, the Channel
Closed on the Digital Bus also pulses for each
channel closure.

Triggering
This example is similar to the previous one except that the multimeter’s
"External Trigger" and "Voltmeter Complete" ports are connected to the
"Channel Closed" and "Channel Advance" on the FET Multiplexer digital
bus. See Chapter 1 for information on making custom digital bus cables.
Once the scanning procedure has been initiated (INIT), the channel closure is
advanced by the handshake lines. The INIT command closes the first
channel, and when the channel is closed, the "Channel Closed" pulses. This
is connected to the "External Trigger" on the multimeter, which triggers a
reading. When the reading is complete, the "Voltmeter Complete" triggers,
which pulses the "Channel Advance". This procedure continues until the
end of the scan list.
The sequence of operation is:
1. TRIG:SOUR DBUS selects digital bus triggering.
2. INIT (line 50) closes channel number 100.
3. The channel closure causes a trigger output from the "Channel

Using the Scan Complete Bit
You can use the Scan Complete Bit (bit 8) in the SCPI Operation Status
Register to determine when a scanning cycle completes (no other bits in the
register apply to the switchbox). Bit 8 has a decimal value of 256 and you
can read it directly with the STAT:OPER? command (refer to the
STATus:OPERation[:EVENt]? command in Chapter 5 for an example).
Note that this is not the same register as the multiplexer Status/Control
Register.
When enabled by the STAT:OPER:ENAB 256 command, the Scan Complete
Bit will be reported as bit 7 of the Status Register. Use the GPIB Serial Poll
or the IEEE 488.2 Common Command *STB? to read the Status Register.
When bit 7 of the status Register is enabled by the *SRE 128 Common
Command to assert an GPIB Service Request (SRQ), you can interrupt the
controller when the Scan Complete Bit is set, after a scanning cycle
completes. This allows the controller to do other operations while the
scanning cycle is in progress.
The following example monitors bit 7 in the Status Register to determine
when the scanning cycle completes. The computer used in the example is
an Series 200/300 used with BASIC as the program language. The
computer interfaces with the mainframe over GPIB. The GPIB select code
is 7, the GPIB primary address is 09, and the GPIB secondary address is 14.

Command Types
Commands are separated into two types: IEEE 488.2 Common Commands
and SCPI Commands.
Common
Command Format
The IEEE 488.2 standard defines the Common Commands that perform
functions like reset, self-test, status byte query, etc. Common Commands
are three or four characters in length, always begin with the asterisk
character (*), and may include one or more parameters. The command
keyword is separated from the first parameter by a space character. Some
examples of Common Commands are shown below:
*RST
SCPI Command
Format
*ESR 32
*STB?
The SCPI commands perform functions like closing switches, making
measurements, querying instrument states or retrieving data. A subsystem
command structure is a hierarchical structure that usually consists of a
top-level (or root) command, one or more lower level commands, and their
parameters. The following example shows part of a typical subsystem:
[ROUTe:]
CLOSe <channel_list>
SCAN <channel_list>
:MODE VOLT
[ROUTe:] is the root command, CLOSe and SCAN are second-level
commands with parameters, and MODE is a third-level command with the
parameter VOLT.
Chapter 5
Agilent E1352A FET Multiplexer Command Reference
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
47
Command Separator
A colon (:) always separates one command from the next lower level
command as shown below:
ROUTe:SCAN:MODE VOLT
Colons separate the root command from the second-level command
(ROUTe:SCAN) and the second-level from the third-level (SCAN:MODE
VOLT). The parameters of a command are separated from the command by
a blank space.
Abbreviated
Commands
The command syntax shows most commands as a mixture of upper and
lower case letters. The upper case letters indicate the abbreviated spelling
for the command. For shorter program lines, send the abbreviated form.
For better program readability, you may send the entire command. The
instrument will accept either the abbreviated form or the entire command.
For example, if the command syntax shows MEASure, then MEAS and
MEASURE are both acceptable forms. Other forms of MEASure, such as
MEASU or MEASUR will generate an error. You may use upper or lower
case letters. Therefore, MEASURE, measure, and MeAsUrE are all
acceptable.
Command keywords can be entered in their full form, as shown above, or
can be entered in their short form. In this manual, the entry required in short
form commands is always capitalized. The short form is generally used for
examples in this manual.
Implied Commands
Implied commands are those which appear in square brackets ([ ]) in the
command syntax. (Note that the brackets are not part of the command and
are not sent to the instrument.) Suppose you send a second level command
but do not send the preceding implied command. In this case, the
instrument assumes you intend to use the implied command and it responds
as if you had sent it. Examine this excerpt from the [ROUTe:] subsystem
shown below:
[ROUTe:]
SCAN <channel_list>
:MODE <mode>
:MODE?
:PORT <port>
Both the root command [ROUTe:] is an implied command. To set the
instrument’s scanning list, you can send either of the following command
statements:
ROUTe:SCAN (@100:131)
Note
48
or
SCAN (@100:131)
You must include a space between the keywords and any parameters.

Parameters
Parameter Types. The following table contains explanations and examples
of parameter types you might see later in this chapter.
Parameter Type
Numeric
Explanations and Examples
Accepts all commonly used decimal representations of
numbers including optional signs, decimal points, and
scientific notation.
123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E-01.
Special cases include MIN, MAX, and DEF. MIN selects
minimum value available, MAX selects maximum value
available, and DEF selects default or reset value.
Boolean
Represents a single binary condition that is either true or false.
1 or ON; 0 or OFF.
Discrete
Selects from a finite number of values. These parameters
use mnemonics to represent each valid setting.
An example is the TRIGger:SOURce <source> command
where source can be BUS, DBUS, EXT, HOLD, or IMM.
Optional Parameters. Parameters shown within square brackets ([ ]) are
optional parameters. (Note that the brackets are not part of the command
and are not sent to the instrument.) If you do not specify a value for an
optional parameter, the instrument chooses a default value. For example,
consider the ARM:COUNt? [<MIN | MAX>] command. If you send the
command without specifying a parameter, the present ARM:COUNt value is
returned. If you send the MIN parameter, the command returns the
minimum count available. If you send the MAX parameter, the command
returns the maximum count available. Be sure to place a space between the
command and the parameter.
Linking Commands
Linking IEEE 488.2 Common Commands with SCPI Commands.
Use a semicolon between the commands. For example:
*RST;OUTP ON or TRIG:SOUR BUS;*TRG
Linking Multiple SCPI Commands. Use both a semicolon and a colon
between the commands. For example:
ARM:COUN 1;:TRIG:SOUR EXT

Boolean
0 | 1 | ON | OFF
• Continuous Scanning Operation: Continuous scanning is enabled
with the INITiate:CONTinuous ON or INITiate:CONTinuous 1
command. Sending the INITiate[:IMMediate] command closes the
first channel in the channel list. Each trigger from a trigger source
selected by the TRIGger:SOURce command advances the scan
through the channel list. A trigger at the end of the channel list
closes the first channel in the list and the scan cycle repeats.
Continuous scanning can be stopped by the ABORt command for
non-downloaded scans, and by a system reset or a power off for
downloaded scan lists.
• Scanning a Set Number of Cycles: The INITiate:CONTinuous OFF
or INITiate:CONTinuous 0 command goes through the scan list the
number of times specified by the ARM:COUNt command. Sending
the INITiate[:IMMediate] command closes the first channel in the
channel list. Each trigger from a trigger source selected by the
TRIGger:SOURce command advances the scan through the channel
list. A trigger at the end of the channel list opens the last channel in
the list, and if the number of cycles has not reached the ARM:COUNt
parameter, returns to the beginning of the scan list and closes the first
channel. When the number of cycles equals the ARM:COUNt
parameter, the scanning cycle stops. Note that ARM:COUNt does not
apply to downloaded scan lists.
• Stopping Continuous Scans: Continuous scanning can be stopped
by the ABORt command for non-downloaded scans, and by a system
reset or a power off for downloaded scan lists.
• Related Commands: ABORt, ARM:COUNt, *RST, TRIGger,

Example
Scanning Using External Instruments
The following example shows how to scan channels using the Agilent
E1300/E1301 Mainframe via GPIB and an Agilent 3457A Digital
Multimeter. This example uses the mainframe "Trig Out" port to
synchronize the multiplexer module in a switchbox to the multimeter. The
trigger pulse from the port triggers the multimeter for a measurement. See
Chapter 3 for typical user connections to the multiplexer.
The computer used in the example is an HP Series 200/300 with BASIC as
the program language. The computer interfaces with the mainframe over
GPIB. Assumed is an GPIB select code of 7, an GPIB primary address of
09 and 22 for the Agilent E1300/E1301 Mainframe and Agilent 3457A
Multimeter, respectively, and an GPIB secondary address of 14 for the
switchbox.

• Enabling the Trigger Source: The TRIGger:SOURce command
only selects the trigger source. The INITiate[:IMMediate] command
enables the trigger source.
• Using the TRIG Command: You can use TRIGger[:IMMediate] to
advance the scan when TRIGger:SOURce BUS or TRIGger:SOURce
HOLD is selected.
• Using Digital Bus Trigger: TRIGger:SOURce DBUS selects the
digital bus on the multiplexer as the trigger. Any open collector TTL
trigger source can be wired to the "Channel Advance" lead. A
negative-going pulse triggers the multiplexer and advances it to the
next channel on the scanning list. After the SETTling:TIME delay,
the multiplexer asserts "Channel Closed" on the digital bus.
• Using External Trigger Inputs: With TRIGger:SOURce EXTernal
selected, only one switchbox at a time can use the external trigger
input at the Agilent E1300/E1301 Mainframe "Event In" port. The
trigger input is assigned to the first switchbox requesting the external
trigger source.
• Assigning External Trigger: A switchbox assigned with
TRIG:SOUR EXT remains assigned to that source until it receives a
command to change the source. When the source is changed, the
external trigger source is available to another switchbox (with a
TRIGger:SOURce EXTernal command). Another switchbox cannot
receive an external trigger source if the source is already assigned, or
an error is generated.
• Using Bus Triggers: To trigger the switchbox with
TRIGger:SOURce BUS selected, use TRIGger[:IMMediate], the IEEE
488.2 common command *TRG or the GPIB Group Execute Trigger
(GET).
• "Trig Out" Port Shared by Switchboxes: See the OUTPut
command.
• Related Commands: [ROUTe:]SCAN, TRIGger, ABORt,
SETTling[:TIME]
• *RST Condition: TRIGger:SOURce IMMediate

Agilent E1352A Register-Based Programming
About This Appendix
The Agilent E1352A 32-Channel Single-Ended FET Multiplexer is a
register-based module which does not support the VXIbus word serial
protocol. When a SCPI command is sent to the multiplexer, the Agilent
E1405/E1406 Command Module (Series C) or Agilent E1300/01
Mainframe (Series B) parses the command and programs the multiplexer at
the register level.
Register-based programming is a series of reads and writes directly to the
multiplexer registers. This increases throughput speed since it eliminates
command parsing and allows the use of an embedded controller. Also, if
slot 0, the resource manager, and the computer interface (GPIB) are
provided by other devices, a C-size system can be down-sized by removing
the Command Module.
This appendix contains the information you need for register-based
programming. The contents include:

Register Addressing
Register addresses for register-based devices are located in the upper 25%
of VXIbus A16 address space. Every VXIbus device (up to 256) is
allocated a 64-byte block of addresses. The Agilent E1352A Multiplexer
uses eight two-byte registers of the 64 addresses allocated.
Figure B-1 shows the register address location within A16. Figure B-2
shows the location of A16 address space in the Agilent E1405/E1406
Command Module and Agilent E1300B/01B Mainframe.
The Base Address
Appendix B
When you are reading or writing to a multiplexer register, a hexadecimal or
decimal register address is specified. This address consists of a base address
plus a register offset. The base address used in register-based programming
depends on whether the A16 address space is outside or inside the Agilent
E1405/E1406 Command Module or Agilent E1300B/01B Mainframe.

A16 Address Space
Outside the
Command Module
or Mainframe
When the Command Module or mainframe is not part of your VXIbus
system (Figure B-1), the multiplexer’s base address is computed as:
C00016 + (LADDR * 64)16
or
49,152 + (LADDR * 64)
where C00016 (49,152) is the starting location of the register addresses,
LADDR is the multiplexer’s logical address, and 64 is the number of
address bytes per VXIbus device. For example, if the multiplexer’s logical
address is 112, the multiplexer will have a base address of:
C00016 + (112 * 64)16
C00016 + 1C0016 = DC0016
or (decimal)
49,152 + (112 * 64)
49,152 + 7,168 = 56,320
A16 Address Space
Inside the
Command Module
or Mainframe
When the A16 address space is inside the command module or mainframe
(Figure B-2), the multiplexer’s base address is computed as:
1FC00016 + (LADDR * 64)16
or
2,080,768 + (LADDR * 64)
where lFC00016 (2,080,768) is the starting location of the VXI A16
addresses, LADDR is the multiplexer’s logical address, and 64 is the
number of address bytes per register-based device. Again, if the
multiplexer’s logical address is 112, the multiplexer will have a base address
of:
1FC00016 + (112 * 64)16
1FC00016 + 1C0016 = 1FDC0016
or
2,080,768 + (112 * 64)
2,080,768 + 7,168 = 2,087,936
Register Offset
The register offset is the register’s location in the block of 64 address bytes.
For example, with a LADDR of 112 the multiplexer’s Scan Channel Delay
Register has an offset of 0816. When you write a command to this register,
the offset is added to the base address to form the register address:
DC0016 + 0816 = DC0816
(A16 outside the command module)
1FDC0016 + 0816 = 1FDC0816 (A16 inside the command module)
or
Appendix B
56,320 + 8 = 56,328
(A16 outside the command module)
2,087,936 + 8 = 2,087,944
(A16 inside the command module)

Card Reset (CRD RST)
Writing a one (1) to bit 0 resets the multiplexer. Writing a zero turns the
reset function off. You must write a zero after a reset or the module will not
operate. The Reset conditions are: all Enables are set false, clear scan list,
scan mode enabled (direct bit set 0), DELAY is l µsec and all channels
opened.
Interrupt Request
Enable (IRQ EN)
Writing a one (1) enables the card to generate interrupts, a zero (0) disables
it. Enabling this bit puts a zero (0) in IRQ EN*.
Direct (DIR)
Selects between direct control and scan list control. A zero (0) indicates
scan list control and a one (1) indicates direct control. For scan list control
the Direct Registers (base + 0C, base + 0E) are invalidated. For direct
control the Scan Channel Configuration Register is invalidated.
Trigger Internal
(TRG INT)
Writing a one (1) immediately advances a channel on the scan list, a zero
(0) is the idle state. Bit is automatically set back to zero (0) upon channel
advance.
Interrupt Request
Enable (IRQ EN*)
Reading a zero (0) indicates enabled, reading a one (1) indicates disabled.
Interrupt Request
(IRQ*)
Reading a zero (0) indicates an interrupt, a one (1) indicates no interrupt.
This bit remains one (1) if IRQ EN is disabled. Interrupt remains set until
Card Reset or interrupt has been acknowledged.
Busy (BSY*)
Appendix B
This bit is set zero (0) during channel closing and the delay period. Triggers
will not be accepted. BSY* is unasserted at the beginning of the Channel
Closed pulse. If a trigger occurs during the Channel Closed pulse, the pulse
is terminated and the channel is advanced. Operates only with downloaded
scan list (DIR is zero).

Clear Scan List
(CLR SCN)
Writing a one (1) in this bit clears the scan list. The bit must be set back to
zero (0) after flushing. CLR SCN (Read) returns the state of the bit.
Digital Bus Enable
(DBS EN)
Writing a one (1) enables the digital bus trigger mode. A zero (0) disables
it. DBS EN (Read) returns the state of the bit.
Immediate Enable
(IMM EN)
Writing a one (1) in this bit sets trigger to immediate, which means that as
soon as the first channel is closed by the TRG INT, the entire scan list is run
without any further triggering. Channel advance speed is determined by the
delay time specified. This has extremely limited applications.
Continuous Enable
(CNT EN)
Writing a one (1) in this bit enables the card to continually cycle through the
scan list. When this bit is enabled, the last channel in a scan list resets the
pointer back to the beginning of the scan list.

Writing a one (1) resets the pointer back to the beginning of the scan list.
CNT EN true automatically resets pointer at end of scan list. If CNT EN is
set true, an interrupt also resets the pointer. If CNT EN is set false, the last
channel in the scan list generates an interrupt if the channel is valid (VLD*
set true).
The Scan Channel Delay Register sets the SETTling:TIME, the time between
receipt of a channel closing trigger and the Channel Closed pulse. The
delay is 2n µS and n has a range of 0 to 15. D3 to D0 set n, and D0 is the
least significant bit. This register is a read-back register, allowing you to
verify the state of the WRITE register.

Executing Commands
This command lists the SCPI commands and shows how to execute them
with register-based programming. For further information on register-based
programming see the Agilent E1326B Multimeter User’s Manual.
ABORt
ABORt does not have an equivalent in register-based programming. This
command is executed from the front panel or over GPIB.
ARM:COUNt
DISPlay:MONitor
INITiate
The ARM:COUNt command does not have an equivalent in register-based
programming. To scan for a specified number of cycles, use the interrupt
generated at the end of the scan list to advance through a program loop for
the set number of cycles. For each pass through the loop, reset the pointer
to the beginning of the scan list. The IRQ EN in the Status/Control Register
must be enabled.
The DISPlay:MONitor[:STATe] command does not have an equivalent in
register-based programming. For high-speed operation it should be set to
DISPlay:MONitor OFF.
INITiate:CONTinuous is equivalent to the CNT EN bit in the Scan Control
Register.
INITiate[:IMMediate] is equivalent to writing a one to the TRG INT in the
Status/Control Register. The TRG INT sets itself back to zero after pulsing
the FET. If you have a multiple-module configuration and a downloaded
scan list, the module with the first channel on the scan list must be the last
one to receive the TRG INT. The scan cycle will start as soon as the card
with a valid channel receives TRG INT.
OUTPut
The OUTPut[:STATe] command does not have an equivalent in
register-based programming.
[ROUTe:]
[ROUTe:]CLOSe <channel_list> is equivalent to the following:
• DIR in the Status/Control Register is enabled.
• D0 to D4 is set to a channel number in the Direct Channel
Configuration Register.
[ROUTe:]OPEN <channel_list> can be implemented by setting VLD* false
in either the Scan Channel Configuration Register or the Direct Control
Register (whichever one closed the channel). It can also be implemented by
toggling the DIR bit in the Status/Control Register.
Appendix B
Agilent E1352A Register-Based Programming
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
85
For [ROUTe:]SCAN <channel_list>, the complete scan list must be loaded
in each module in a multiple-module configuration. The channel is set valid
if it is in that module, and invalid in the other modules. The channel list is
downloaded in the following way:
• Set CLR SCN in Scan Control Register to one, then back to zero, to
clear the previous scan list.
• DIR in the Status/Control Register is set to false.
• Channel number is set in D0 to D4 in the Scan Channel
Configuration Register.
The example below shows how to set a scan list for channels
(@100,101,200,201):
• Write to the Scan Channel Configuration Register on card 1:
VLD* true (0), 0000 to D4-D0
VLD* true (0), 0001 to D4-D0
VLD* false (1), XXXX to D4-D0
VLD* false (1), XXXX to D4-D0
Sets channel 100
Sets channel 101
Reserves position in scan list for
channel 200
Reserves position in scan list for
channel 201
• Write to the Scan Channel Configuration Register on card 2:
VLD* false (1 ), XXXX to D4-D0
VLD* false (1 ), XXXX to D4-D0
VLD* true (0), 0000 to D4-D0
VLD* true (0), 0001 to D4-D0
Reserves position in scan list for
channel 100
Reserves position in scan list for
channel 101
Sets channel 200
Sets channel 201
The [ROUTe:]SCAN:MODE VOLT | RES is set with C0 in the Scan
Channel Configuration Register or Direct Control Register.
C0

Volts
2-wire ohms
[ROUTe:]SCAN:PORT NONE | ABUS is set with A_D* and B_D* on the
Scan Channel Configuration or Direct Control Registers. Set both bits to
one for ABUS and to zero for NONE.
[ROUTe:]SETTling[:TIME] is set with the D3 to D0 bits in the Scan
Channel Delay Register. The bits form a number n (n is between 0 and 16),
and the delay is 2n µsec.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
SYSTem
SYSTem:CDEScription? is a READ on the Manufacturer ID Register.
SYSTem:CTYPe? is a READ on the Device Type Register.
SYSTem:CPON can be achieved by setting the DIR bit true in the
Status/Control Register and setting VLD* false. This opens all channels
without a card reset.
TRIGger
TRIGger[:IMMediate] is equivalent to writing a one to TRG INT in the
Status Control Register. The register returns to zero after pulsing the
channel.
TRIGger:SOURce IMMediate and TRIGger:SOURce DBUS are executed
with the IMM EN and DBS EN bits in the Scan Control Register.
TRIGger:SOURce BUS and TRIGger:SOURce EXTernal are not
implemented at the register level. These commands both write to the TRG
INT bit when they are active and a trigger occurs.
TRIGger:SOURce HOLD is not implemented at the register level. It is in
the normal state when all trigger sources are disabled.
